I just ran this line through pronterface.
G29 V4 n4 F25 B175 L25 R175
It hits 25mm within the ends of the bed. It does a pretty good job of getting the platform covered with samples.
Although I could push it further out, I think it would be getting too close for comfort.
I will be using that line in my Pre Gcode until the new release of marlin. I am ok with that.
Here is my pronterface returns.

The matrix seems to tell me that the bed is very flat, just very tilted, but that is OK with me.
Would like to hear your thoughts Roxy.
